Soft Roll type lithium ion battery is the lithium ion battery that most probable is prepared into flexible type, general Soft Roll type lithium from Sub- battery uses aluminum plastic film as wrapping film.Since battery is due to itself there is certain thickness, this results in battery being bent When there are the differences of interior bent face and outer bent face.Two faces difference as existing for internal-and external diameter in bending, in bending process wherein Aluminum plastic film on one side can show the trend of contraction, alleviate due to not having region to this trend, aluminum plastic film will be in electricity There is folding line in certain position in pond, and in the case where alternating bending, folding line can gradually rupture, and the position ruptured is often The position that stress is most concentrated.
Summary of the invention
In order to overcome the shortcomings of the prior art described above, the object of the present invention is to provide one kind to be suitable for flexible Encapsulation end socket, packaging method and the battery of battery, can effective dispersed cell bending when the stress that generates, prevent to occur Aluminum plastic film rupture is so as to cause battery leakage, failure and causes possible safety problem.
To achieve the above object, the technical scheme is that a kind of encapsulation end socket suitable for flexible battery, The upper cover and lower head being correspondingly set up and down;The upper cover is close close to the side of naked battery core side and the lower head The side of naked battery core side is uniformly arranged multiple arcs protrusion, on the arc convex and the lower head on the upper cover Arc convex corresponds, and the protrusion direction of the arc convex is towards the naked battery core.
Further, arc groove is formed between the two adjacent arc convex.
Further, the arc convex replaces to be smoothly connected to form wave structure with the arc groove.
Further, the arc convex is waveform or arc-shaped, and the arc groove is waveform or arc-shaped.
Further, the shape of the arc convex is identical as the shape of the arc groove.
